Abstract
A technique facilitates application of increased force on a downhole tool, such as a shifting tool. According to an embodiment, a shifting tool is sized for deployment along the interior of a well string to enable shifting of a sliding sleeve. The shifting tool comprises a plurality of keys which are movably mounted for actuation between a contracted position and an extended position engaging the sliding sleeve. A plurality of pads may be actuated with the plurality of keys so as to form a flow restriction between the shifting tool and the surrounding well string. As a result, fluid pumped down between the shifting tool and the well string establishes a pressure differential across the flow restriction which helps move the shifting tool and the sliding sleeve to a desired position.
